Question Is this 550W PSU enough for a RTX 3060 12GB?

Hi, I'm planning to upgrade my GTX 1650 Super to a RTX 3060 12 GB. I'm currently using a MSI MAG A550BN 550W 80+ Bronze as my PSU.
I wonder if it's enough to power an RTX 3060. Here are the other system components,

CPU: Intel® Core™ i5-10400F @ 2.90GHz
RAM: Corsair Vengeance LPX 16GB DDR4 3200Mhz (16GB x 1)
MoBo: MSI B560M PRO-E
Storage:
Kingston NV1 NVMe PCIe SSD M.2 2280 250GB
Crucial BX500 1TB 3D NAND SATA 2.5-Inch Internal SSD

That MSI MAG power supply is a higher tier unit. It'll be more than sufficient for an RTX 3060.

A useful site when putting together parts for a build is PCPartPicker.com. It has a power calculator and will tell you the estimated power requirements of the system. Here is what it shows for your build with a 3060 12GB:

329 Watts

By the way I noticed you only have 1 stick of RAM. Adding a second stick could offer a pretty decent boost in performance as you would go from single channel to dual channel. Consider picking up a second matching stick at some point and make sure you have XMP enabled in the BIOS.

Like In2Photos said, you REALLY need to get a second preferably identical 16GB stick of ram to put in that system. Single Channel performance vs. Dual Channel can be quite large and far less stuttering and jerkiness in games.
